Main aliases:	Midwife from hell (female)
Biological type:	Metamorphic humanoids
Appearances:	TW: Something Borrowed

The Nostrovites were a race of metamorphic humanoids.

Biology

The Nostrovites, in their natural form, appeared to vaguely resemble a near-Human, but with red eyes, sharp claws and teeth, and visible blood vessels. Nostrovites were carnivores, but only ate living flesh and would normally ignore corpses. The females, at least, could create a sticky, web-like structure to keep prey alive until they were hungry again. The blood of the Nostrovites was black. (TW: Something Borrowed)

Their brains were located in their abdomen. (WEB: torchwood.org.uk)

With the use of their proteus glands, they could adopt other humanoid forms. (TW: Something Borrowed) Owen Harper believed that they would require genetic samples from the form they wanted to take. He also believed that they had genetically modified themselves to be able to shapeshift or that they were a composite race that had taken the proteus gland from another species.

Life Cycle

The Nostrovites, like many other species, had two sexes - male and female. However, they also required a third member: a host. After fertilising the female's eggs, the male would take the eggs and store them in a sack in his mouth. After finding a potential host, the male would bite them and inject the eggs into the host's bloodstream. The eggs would quickly develop inside the host as if the host was merely pregnant with another of its species.

After a while, the female would track down the host and tear them open to release the young. This process is Nostrovite childbirth.

They became very resilient, and it was shown that several rounds of bullets had little effect on a female Nostrovite. (TW: Something Borrowed

History

The Nostrovites were familar to Jack Harkness, although he never said whether this was to do with prior experiences in his native time or with Torchwood 3.

At some point in their history, some Nostrovites discovered Earth and developed a taste for Human flesh. At least one pair reproduced and used Torchwood operative Gwen Cooper as a host. The male was killed by Jack. The egg passed through the bite and grew in Gwen's belly. The day after the attack was Gwen's wedding, which she went through with even though the female was still out there. The female Nostrovite planned to get her child by opening Gwen's belly. The female posed as a normal women, Rhys's mum and captain Jack Harkness to get closer to Gwen. She then gets shot by Owen, smells him, learns he is already dead, and leaves.

The Nostrovite turns into Rhy's mum Brenda Williams which the torchwood team finds, Gwen shoots her and she runs away. Later Gwen and Rhys were trapped in a hut, she breaks in but gets killed by Jack with a gun and the developing young is removed by Rhys Williams using the Singularity Scalpel. (TW: Something Borrowed)
